In this week's lab, we were introduced ERDAS Imagine. I began with basic tasks, including learning the a few tools and how to use the viewer. EDRAS is used for remote sensing and image processing tasks with satellite or aerial images. Map 1 was created in a two-step process using both ERDAS Imagine and ArcGIS Pro.
The map illustrates a small area of a Landsat Thematic (TM) image that contained 7 bands of multispectral imagery at 30 meter resolution. In ERDAS, I selected a smaller section of the original image for exportation, after I created a new field in the attribute table to calculate the total hectares of each of the multispectral bands, or "classes" of the subset. Each class shows the distribution of different surface features, such as vegetation, clouds, and water across a section of mountains.
The data was exported to ArcGIS Pro as the program is ideal for map production.
